摘要

para-Trifluorovinyl α, β, β-trifluorostyrene (1-CF= CF2), p-acetoxy α, β, β-trifluorostyrene (1- AcO) and p-vinyl α, β, β-trifluorostyrene (1-CH= CH2) have been synthesized. The rate constants (k) for the thermal cyclodimerization of 1-CF= CF2 and 1-AcO have been measured over the temperature range 90–130° C for 1-CF= CF2 and 110–160° C for 1-AcO. The σmb polar substituent constants of the p-CF= CF2, pCH= CH2 and p-AcO groups ...
